T 0 all whom it may concern Be it known that I, DELAWnRE J ..HooD, a, citizen of the United. States, and a residentof the city of Philadelphia, Pennsylvania, have invented certain new and useful IIn rovements in Taliring-ldachines, of which t e following is a full, clear, and complete disclosure, reference being had to the accompanying drawings, forming a part of this specification, this ilication being a division of my application 'hled QctoberS, 1904, Serial No. 227,624.

The main objects of my invention are to provide improved means, of simple, durable construction, for connecting a sound box to a hollow sound conveying arm, and which will rovide improved means for holding the styus needle 11'). contact-with. the record; and to provide other improvements. which-will ap pear in the following specification.

In the accompanying drawings: Figure 1 is a fragmentary side elevation of a sound box and sound conveying arm constructed in accordance with this invention, showing the same in its operative relation to a record tablet; Fig. 2 a similar view partially in section; 1plan view of the. ig. 4 a top plan view of the same but showing the sound box rotated into position for changing riedles3, Fig. 5 a transverse section of. the stylus bar oscillation of the bar and Fig. 6 isa side ele,

accordance with this invention.

Referring to the drawings, the device com-' prises a sound box 1, of the type used in con.- ncction with sound records having lateral undulations and a. hollow sound conveying swinging arm or tube 2 which is pivoted at its larger or inner end 2 in a well known manner to swing in a lane arallel to the disk record 3, of the latera y undulating groove type, which is mounted to rotate upon the usual cabinet 3.

For rotatably connecting the sound box with the swinging arm 2, the end ofthe arm 2 a. is 'n'ovided with a short transverse sleeve or -tu e 4 communicating therewith which is adapted to telescope over the outerend of a tube or bushing 4 which forms a reduced extension of the rear side of the soundboi; casv Specification of Letters Patent.

Original application filed Qctubcz' 8, 1901, Serial No. 227,624. Divided and. this application filed April Serial No.

.upon a. torsional spring Patented Dec. 22, 1908.

inner tube 4 is thus held rotatably in posi-- tion in the outer tube 4. By thismeans the sound box is mounted to swing in a plane parallel to the face of the record 3 and to rotate on an axis coincident with the longitudinal axis of the tube 4, substantially parallel to the face of the record 3 and substantially perpendicular to the longitudinal axis of the swinging arm 2.

The'mounting for the stylus bar comprises a tube 9 projecting radiallyand rigidly from the sound box "casing and communicating therewith, and the stylus bar 10 extends within and axially of the tube 9 and is spaced from the inner surface of the tube. The stylus bar is elongated to correspond to the len th of the containing tube 9. The inner 611 ar 15 mounltedto oscillate 1-2 which extends diametrically'of the outer end ofthe tube 9,

outer end of the the sprin being fixed rigidly both to the bar and to t e tube. The stylus bar has the usual socket and set screw 13 for holding the stylus needle 15 in position.

As the present embodiment of this in: vention the sound box s restrained to swing in a plane parallel to the face of the record, it is necessary to have some means for holding the stylus needle yieldin'gly in contact with the record groove with sufficient pressure to produce .the best results. For this purpose the walls of the tube 9 are made sufficient weight to give by gravity the desired turning movement to the sound box when the sound box is in operative position as shown in Figs. 1 and 2.

It is apparent that the radial tube 9 on the sound box serves not only as a weight to hold :the st lus-needle in contact with the record, but a so serves as a protector for the stylus bar, and, also enables an elongated bar to be used having its axisof oscillation spaced at a -greater distance than usualfroni the inner .80 of the stylus bar is phonetically connect'ed to the diaphragm 11 as usual and the tate the operation of chan ing needles and withan' a' ally pivoted sound box casing, of

end of the bar, thus increasing the amplitude 'of vibration of the diaphragm in reproducing.

When it is desired to' change needles the sound box is rotated into the position shown in Fig. 4, and, obviously, stops 16 may be employed for limiting this movement of the sound box so that the stylus bar may be retained in a raised inverted position to facilialso to keep the stylus needle away-from the record when the machine is not in use.

It is evident that in the connection provided bythis invention between the sound box and the swinging sound conveying arm there would be but little frictionbetween the moving parts, that the passages are short and conveniently shaped, and that it wouldnot be necessary to lift any of the weight of the body of the soundbox in changing needles or in removing the needle from the record.

Although'I have described only one form in which this invention may-be embodied, it is obvious that many changes might be made in the construction herein set forth, within the scope of the appended claims, to adapt the invention to different requirements and diflerent types of talking machines, without departing from the spirit of this invention or sacrificing any of the advantages thereof.
